The one bonus to the Spyder hubs bolt pattern is it opens up a larger selection of wheels. The 4 1/4" PCD was used on more cars compared to the Triumph/Lotus 3 3/4" PCD. But, finding a rear hub with the 4 1/4" PCD that fits the stock Lotus rear hub set up might prove a bit difficult. Though, with the VW bits that are being discussed in the technical forum that may prove to be an easy way to get the 4 1/4" PCD (redrill the VW ones).
